Hybrid tea rose plant named `Interzena`

ABSTRACT

A new variety of hybrid tea rose plant producing pink blend flowers.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose of the hybrid tea rose class which was originated by my crossing as seed parents two unnamed, unpatented, undistributed, proprietary seedlings of my creation. The varietal denomination of this new rose is `Interzena`.

Among the novel characteristics possessed by this new variety which distinguishes it from its parents are its ability to produce commercially desirable cut flowers for the cut flower market. Plants of the new variety have attractive foliage and produce flowers of good bud and flower form.

Asexual reproduction by budding and grafting of the new variety as performed in Watsonville, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows typical specimens of the flowers and vegetative growth of the new variety depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character. Phenotypic expression, including colors, may vary depending upon growing conditions, such as climate, soil, and environmental conditions.

DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of my new variety, with color terminology in accordance with The Royal Horticultural Society Color Chart (R.H.S.C.C.). The terminology used in color description herein refers to plate numbers in the aforementioned color chart. Where general terms such as average, normal, ordinary, medium, etc. are used, the characteristics so described are not considered distinguishing.
